HCB20-500-RC

Chip Ferrite Bead Overview

The HCB20-500-RC is a surface mount EMI suppression component manufactured by Allied Components International. It functions as a ferrite bead with an impedance of 50 ohms at 100 MHz and a tolerance of ±25%. The device is housed in a 1206 package and supports a current rating of 3A with a maximum DC resistance of 25 milliohms. It operates within a temperature range of -55°C to +125°C and complies with ROHS standards.

Chip Ferrite Bead Feature Summary

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value at 100 MHz and the DC resistance limit against the official datasheet before procurement. Confirm that the 1206 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for ROHS compliance documentation if required by regulatory standards.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance is critical to minimize power loss while maintaining effective high-frequency noise attenuation. The 3A current rating suits moderate power applications. Consider the 1206 form factor for standard SMD assembly processes. Evaluate the ±25% impedance tolerance to ensure it aligns with the circuit's noise rejection specifications.

Chip Ferrite Bead Part Context

This part belongs to the HCB20 series of high current beads from Allied Components International. The series includes variants such as HCB20-50 and HCB20-800-RC, offering different impedance levels. These components are categorized as surface mount EMI suppression devices designed for compact electronic designs requiring reliable noise filtering.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 1206 ferrite beads with similar 50 ohm impedance at 100 MHz and comparable current ratings. Verify that alternative parts maintain the same physical footprint and thermal characteristics to ensure compatibility without redesigning the PCB layout.
